Most would agree that documentary style horror is an overdone genre. For every good one, there are at least 10 that are just derivative. But they're cheap to make, and if done right can be very effective and entertaining. And Digging Up the Marrow is very entertaining.
Real life horror film writer/director Adam Green receives lots of fan mail from his cult followers, some more bizarre than others. But when he receives a plea from a man who believes he has found real life monsters and wants his help to film them, it's too appealing an offer not to pursue. But has the man actually found them, or is he just crazy? The formula may be tired, but the execution here is flawless, and helped largely by character actor Ray Wise. It's good, creepy fun and you can see it at home on Video on Demand.
Who is this movie for? Fans of documentary style, found footage, and genre films will probably be very entertained.
